In order to boot Arch Linux, you must install a Linux-capable boot loader to the Master Boot Record or the GUID Partition Table. The boot loader is the first piece of software started by the BIOS or UEFI. It is responsible for loading the kernel with the wanted kernel parameters, and initial RAM disk before initiating the boot process. See below for boot loaders available.
Feature comparison
Note:
- Boot loaders only need to support the file system on which kernel and initramfs reside (the file system on which
/bootis located). - As GPT is part of the UEFI specification, all UEFI boot loaders support GPT disks. GPT on BIOS systems is possible, using either "hybrid booting", or the new GPT-only protocol. This protocol may however cause issues with certain BIOS implementations; see rodsbooks for details.
- Encryption mentioned in file system support is filesystem-level encryption, it has no bearing on block-level encryption.
